'Game of Thrones' season preview promises chaos

No series on television is quite as coy as "Game of Thrones." The HBO drama, still a little more than a month off of its March 31 season three premiere, has dropped a promo -- but it's no more telling than the ones before it.

It is, however, full of the familiar faces and cryptic narration that fans have come to expect from "Game of Thrones."

"Chaos isn't a pit. Chaos is a ladder," says the voice of Littlefinger (Aidan Gillen) as the different characters' images fade in and out of view. "Many who try to climb it fail, never get to try again. The fall breaks them. And some, given a chance to climb, they cling to the realm, or the gods or love. Only the ladder is real. The climb is all there is."
